DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 454,004, dated June 9,1891. Application filed February 12, 1891. Serial No. 381,138. (Nomodel.)

To all whom it may concern:

Belit known that I, JAMES A. KLEES, a citizen of the United States,residing at Reading, in the county of Berks, State of Pennsylvania, haveinvented certain Improvements in Dumping-\Vagons, of which the followingis a specification.

This invention relates to dumping-wagons having their bodies pivotallyconnected to the wagon-frame by means of elevating-arms, by theoperation of which they are raised vertically preparatory to dumping,and more especially to those in which practically the whole load of theelevated body is supported at a single point of the frame.

My main object is to so construct the frames with relation to theelevating mechanism as to secure with a minimum of material amplestrength at the point of greatest strain and provide at the same time amost convenient connection for said mechanism.

A further object is to provide an improved device for locking thewagon-bedin any position to which it may be elevated.

The invention is fully described in connection with the accompanyingdrawings, and is specifically pointed out in the claims.

Figure 1 is an elevation showing the near frame, &c., removed, thusgiving a full inside view of the off frame. The body is indicated in twopositionsthat is, as resting directly on the frame, and also as partlyelevatedthus showing the action of the lockingmechanism. Fig. 2 is asection on the line X X of Fig. 1 and gives'another view of this lockingmechanism.

The general features of the wagon illustrated in the drawings consist ofthe usual movable body, of which the bed E only is shown, the frames A,mounted in any suitable manner on the wheels, the center of the rearpair of which is at W, the elevating-arms G, pivoted at one end to theframe and at the other 9 to the movable bed E, and the mechanism forlifting the forward ends of the arms G to elevate the bed.

In the present construction the main portion of the frames Aare lighttimbers of uniform section throughout their length. To these timbers,preferably upon their interior faces, I secure irons B, of substantiallytriangular shape, having their greatest depth at a point I) about midwayof the length of the frame,(the forward end of which is not shown,)which point extends considerably below the frame, while the top edge ofthe iron corresponds with the top line of the frame. Openings Z) inthese irons below the frame Aserve as bearings to support thecross-shaft H, by the rotation of which the elevating-arms G areoperated through connectingchains. (Not shown.) At either side of thesebearings the irons are lightened by cutting triangular openings b thusforming truss-irons, in which the lower inclined members 19 are placedin o 5 tension by the weight of the raised body of the wagon transferredthereto through the shaft H,while the horizontal upper portion, togetherwith the frame A, to which it is secured, is placed in compression bythe same weight, thus giving great transverse strength to the frames andeffectually preventing any bending or distortion due to the raising ofthe bed. Each elevating-arm G is pivoted to the frame atOby means of aboltpassingthrough the frame and the iron B, and an extension 0 of thisbolt on the outside of one of the frames serves as the point ofattachment for the rod D, by means of which the bed E, to which it isalso connected at e, is conveniently locked at any height from the frameA to prevent tilting upon its pivotal connection with the elevating-armsat 9. When the bed is in its normal position, resting upon the frame A,this rod D approaches a horizontal position, the projections c and 6being almost in line,

as well as at their nearest approach to each other. The slots d and 01,extending from near either end of the rod toward each other, permit therod to assume this position when 0 the bed is lowered. As the bed islifted by raising the arms Gr the projection e rides in the slot cluntil it strikes the closed end of the red, when the continued elevationof the bed causes the lower slotted end (1' of the rod 5 to move on theprojection c. When the desired height is reached, it is only necessaryto turn the nut f on the bolt 0 to prevent the rear end from tiltingupward, and if the conditions require ita similar nut can be used at eto prevent tilting in the opposite direction.

The multiplying-gear, by means of which the shaft H is rotated and thearms G raised, is secured to one of the frames A by means of abearing-iron K, fastened to the inside face of the frame and having adepending ear 7;, in which the extended end of the shaft II issupported. The turning of the crank L operates the latter through thegearing 1 2 3 4, arranged in any ordinary manner.

By means of my construction the frames are made absolutely secureagainst deflection by the use of a minimum amount of material, and themain operating parts are conveniently and advantageouslyattached to thesame irons which impart this strength to the structure. The locking-rodmoves up and down automatically with the bed, and the slightest turn ofanut serves to lock or release it.

I am aware that it is not new to attach metal plates to the sides of thewagon-frame and to form journals for the operating-shaft in said plates,and I do not claim such construction as my invention.

What I claim is- 1. A dumping-wagon having a movable bed pivotallysupported upon elevating'arms, an operating-shaft and multiple geartherefor for lifting said arms, and a locking-rod D, connecting themovable bed and frame, said shaft being supported in bearings formed inmetal truss-plates B, which are bolted against a vertical face of eachframe, and said arms and locking-bar being also pivotally connected tosaid truss-plates, substantially in the manner and for the purpose setforth.

2. In adumping-wagon having a movable bed pivotallysupported uponelevating-arms, the locking mechanism consisting of the rod D, havingslots extending longitudinallyfrom either end for a limited distance,pivotal projections from the wagon body and frame entering said slots,respectively, and means for binding the rod, substantially as set forth.

In testimony whereof Iafiix my signature in presence of two witnesses.

JAMES A. KLEES.
